Previously undescribed molecular mechanisms of resistance will emerge with the increased use of cyclin-dependent kinase 4/6 inhibitors in clinical settings. To identify genomic aberrations in circulating tumor DNA associated with treatment resistance in palbociclib-treated metastatic breast cancer (MBC) patients, we collected 35 pre- and post-treatment blood samples from 16 patients with estrogen receptor-positive (ER) MBC, including 9 with inflammatory breast cancer (IBC). Circulating cell-free DNAs (cfDNAs) were isolated for sequencing using a targeted panel of 91 genes.

- Radiation therapy technologists (RTTs) experience high levels of stress and burnout, which were evaluated through a national survey in Italy before and during the pandemic.
- The study utilized the Maslach Burnout Inventory to measure emotional exhaustion, depersonalization, and personal accomplishment, finding consistently high levels of emotional exhaustion and depersonalization among RTTs.
- Results indicated that factors such as being female, having children, and working with pediatric patients were related to increased emotional exhaustion and lower personal accomplishment, suggesting the need for targeted interventions to address burnout in the profession.

Purpose: Interventional radiotherapy (IRT, brachytherapy and intra-operative radiotherapy) is a complex treatment approach that requires a multi-professional approach. The aim of this work was to assess the role of radiation therapy technologist (RTT) in IRT team, with a special focus on brachytherapy as well as to define more appropriate ways to improve skills and training to promote cooperation of multi-professional team.
Material And Methods: A nationwide survey consisting of 16 questions was proposed between April and May 2020, with collaboration between the Italian Association of Radiation Therapy and Medical Physics Technologists (AITRO) and the Interventional Radiotherapy Study Group of Italian Association of Radiotherapy and Clinical Oncology (AIRO).
Purpose: To assess the dosimetric advantages of apertures in intracranial single fraction proton radiosurgery.
Materials And Methods: Six neuroma and 10 meningioma patients were investigated. For each patient, six plans were computed, with two spot spacing and three aperture settings (no apertures, 5 and 8 mm margin between aperture and clinical target volume [CTV]).
Purpose: To perform the validation of the GPU-based (Graphical Processing Unit based) proton Monte Carlo (MC) dose engine implemented in a commercial TPS (RayStation 10B) and to report final dose calculation times for clinical cases.
Materials And Methods: 440 patients treated at the Proton Therapy Center of Trento, Italy, between 2018 and 2019 were selected for this study. 636 approved plans with 3361 beams computed with the clinically implemented CPU-MC dose engine (version 4.
